Graphene-impregnated microfiber fabrics and methods for producing such fabrics are disclosed. In one example, a method of producing a graphene-impregnated microfiber fabric comprises providing a microfiber substrate comprising polymer fibers. Graphene is mixed into a polymer-based dispersion to create a graphene-impregnated polymer-based dispersion. The graphene-impregnated microfiber fabric is formed by immersing the microfiber substrate in the graphene-impregnated polymer-based dispersion to coat the polymer fibers of the substrate with the graphene and the polymer of the polymer-based dispersion. The fabric is removed from the dispersion and dried.
